My invention relates to a new and useful improvement in a curling rodfor permanent waving and has for its object the provision of a curlingrod structure which will be simple in structure, economical ofmanufacture, durable, highly eilicient in use, and easily operated.Another object of the invention is the provision of a curling rodwhereby the end thereof may be brought into close relation with thescalp and in which a burning of the scalp, either through direct contactor by escaping` of steam, is prevented.

Another object of the invention is the provision of a curling rod ofthis class in which the various parts may be easily and quicklyassembled.

Another object of the invention is the provision of a structure wherebythe curling parts may be locked in position -when the hair is wound uponthe rod.

Another object of the invention is the provision of a structure for usein connection with a curling rod which will serve to provide areceptacle for the reception of any condensate which may be formed andwhich will serve as a guard against the escape of steam toward thescalp.

Another object of the invention is the provision of a pair of relativelymovable hair locking parts which may be easily and quickly securedinposition and which will always move to a pre-determined location so thatthe entry slots will be in alignment for the passage of a wisp of hairthereinto.

1n the invention I use a curling rod 12 which is secured to and projectscentrally upwardly from the base of a cup-.shaped member 13 having theupstanding inwardly inclined flange or side walls 14. A notch 15 isformed inwardly of this cupshaped member terminating in an elongatedslot. A cup-shaped member 17 is adapted to t over the cup-shaped member13. The upstanding flange or side wall 19 of the cup-shaped member 17 isalso inclined. An opening or notch 18 is formed in the cup-shaped member17 to conform to the contour of the opening or notch 15 and this openingor notch 18 terminates in an elongated slot 18 which is faced oppositelyto the notch or slot 16. The member 17 is "fastened on the member 13solely by its frictional engagement therewith, the member 17 snappingonto the member 13 and to this end the member 17 must be made of metalsuiiiciently resilient for this purpose. When the parts are assembled inthis manner, as shown in Fig. l2, and rotated relatively to each otheruntil the pin 21 which projects downwardly from the base of the member13 and which rides in the groove 20 formed in the upper surface of thebase of the cup-shaped member 17 has reached the end of the groove theopenings or notches 18 and 15 will be in alignment so that a wisp ofhair may be inserted into these openings. Thereupon, the disc orcupshaped member 17 will be rotated relatively to the disc or cup-shapedmember 13. In Fig. 4 these cup-shaped members are shown in alignment andthe wisp 45 of hair has been moved into the space provided. In Fig. 5 arelative rotation of these members has been eiected so that the wisp ofhair engages in the slots 16 and 13' and it will be noted that the wispof hair is shaped into arcuate form to partly embrace the curling rod12. In order to lock these parts 13 and 17 in position to retain thewisp of hair and prevent any undue movement of the parts the set screw22 carried by the flange 19 is threaded against the flange 14', whichprevents relative rotation of the members 13 and 17. A. cup-shapedretainer 40 is clamped about the disc 17 and secured to the outersurface of the base of the cup-shaped retainer 40, which is alsoprovided with an inclined resilient wall 41, is a layer 42 of heatinsulating material and a layer 43 also of heat insulating material butsoft and yieldable such as a layer of felt, leather, or the like. Thislayer 43 will engage closely against the scalp and since lthere are nooutward projections from the asinto steam.

sembly the layer 43 may be brought into close engagement with the scalp.Where a number of these curling rods are used, and in giving a permanentwave a large number is always used, the curling of the hair with eachrod consequently is begun at a common distance from the scalp so thatuniformity of the curl is possible and a more even and symmetricaldistribution and progression of the waves in the hair is effected.

The layer 23 is formed from felt or other suitable lnaterial and hasslits 24 projecting inwardly, these slits being extended at right anglesto each other and crossing so that a central opening is formed in thelayer 23, which is placed in the cup-shaped member 13 in embracingrelation to the rod 12 and the hair wound therein. This layer 23 servesas a sealing gasket and its purpose will appear hereinafter.

In order to wind the hair about the rod 12 I provide a winding deviceconsisting of a metal plate doubled upon itself to provide the overlyingportions 29 and 30 which embrace and securely grip the rod 12. Each ofthese doubled over portions is provided at its edge with knuckles 31 and32 in each of which is positioned a wire 33 and 34. respectively whichare formed into a gripping hook 35. The wisp of hair is engaged by thehook 35 and upon a rotation of this hook about the rod l2 the hair iswound firmly around the rod 12. The lower edge 36 of these doubled overmembers 29 and 30 is inclined so that as the wisp of hair is wound uponthe rod 12 the winding member will, through engagement of the inclinedsurface 36 with the wisp of hair wound on the rod, travel outwardly andthus a uniform winding of the wisp upon the rod is effected.

After the wisp of hair has been wound upon the rod 12 it is covered withthe layers 3'7 of absorbent pads or cloth saturated with the liquidwhich it is desired to use to produce, in co-operation with the heat,the permanent curl or wave. In carrying out the operation a heatingelement 38 provided with the insulating sheath or apron 39 isused.Vifhen the heat is applied, the liquid carried by the pads 37 isvaporized and turned It is quite necessary that none of this steam bepermitted to pass downwardly into engagement with the scalp and it isalso quite desirable that none of the condensate may reach the scalpwhile in a hot condition. To this end the layer -23 serves to functionin conjunction with a receptacle forming sleeve 25 which is positionedin concentric relation to the rod l2, as shown in Fig. 3. This sleeve 25is provided at one end with the outwardly projecting flange 26 having atone point the nose or projection 2'?. In assembly, the sleeve is placedin position by turning the same until the nose 27 is in alignment withthe opening 15 whereupon the flange 26 may be pressed rmly intoengagement with the layer 23 which serves as a sealing gasket or washer.A rotation of the sleeve relatively to the member 13 will lock theseparts together through the engagement of the nose or projection 27beneath the flange 14. In this way I provide a tight seal by pressingthe layer 23 firmly between the base of the cup-shaped member 13 and theilange 26 so that passage of liquid or steam downwardly into engagementwith the scalp is prevented.

The device is one which is compact and very easily and quickly assembledeven by an unskilled person. Even with unskilled labor the device may beused without danger of burning the scalp as it is impossible for leakageto occur, the seal referred to being suciently tight for all purposes.The device may also be used with any type of curling machine and thewinding member serves to eliminate all necessity of tying the hair onthe prong. By having the winding member formed from the pair of doubledover resilient parts 29 and 30 the winding member may be used on curlingrods of diierent size and dimensions. In this way I have provided acurling rod assembly which is adapted for universal use which iseffective of a higher grade work than can be accomplished with curlingrods now in use and which is absolutely safe so far as burning of thescalp is concerned.

VWhile I have illustrated and described the preferred form of myinvention, I do not wish to limit myself to the precise details ofstructure shown, but desire to avail myself of such variations andmodifications as may come within the scope of the appended claims.
